However, often the depth, release, and rate of chest compressions are controlled subjectively by the nurse. &nbsp;This study aimed to investigate the effect of chest compression feedback (CCF) by nurses using a Cardiopulmonary Resuscitation (CPR) meter on the Return of Spontaneous Circulation (ROSC) in patients undergoing CPR admitted to the intensive care units.</span><br> <span style="unicode-bidi:embed"><b>Methods: </b>This single-blinded, two-arm parallel randomized clinical trial was conducted on 70 patients undergoing cardiopulmonary resuscitation who were admitted to the intensive care unit of the Iraqi-Korean Specialized Intensive Care Hospital in Baghdad, Iraq. The patients were randomly allocated to the experimental and control groups (35 subjects per group). Feedback was given to the nurses in the experimental group by a CPR meter as soon as CPR began. Patients in the control group received routine CPR.<b> &nbsp;</b>To assess the key indicators of ROSC, including blood pressure, pulse, and End-Tidal Carbon Dioxide (ETCO2), we recorded ROSC rates at 5, 10, 15, 20, and 30 minutes following CPR. The measurements and data collection were conducted according to the Utstein Style Guidelines. Subsequently, data on sustained ROSC, blood pressure, pulse, and ETCO2 were analyzed to ensure accuracy and comparability based on these guidelines. Statistical analysis was performed using SPSS software (V.24). Independent t-test, Chi-square test, and repeated measures ANOVA were employed to analyze the data. The significance level was set at p < 0.05.</span><br> <span style="unicode-bidi:embed"><b>Results: </b>The percentages of spontaneous blood flow return after 30 minutes of resuscitation were 17.55% and 14.35% in the experimental and control groups, respectively. Within-group comparison showed a significant difference in the blood pressure, pulse, and ETCO2 of both groups in the time interval of five minutes to 30 minutes after the start of CPR. Between-group comparison showed significant differences in the patients&#39; blood pressure and pulse in all time intervals, except for the first five minutes. The ETCO2 difference was only significant after 10 and 30 minutes of CPR. <span dir="RTL" lang="FA"><span style="font-family:"Times New Roman",serif"></span></span></span><br> <span style="unicode-bidi:embed"><b>Conclusion: </b>Providing feedback to nurses by CPR meters provides an effective method to increase the quality of CPR and return of spontaneous circulation of patients.</span></span></span></span></div> Cardiopulmonary resuscitation Feedback, Return of Spontaneous Circulation, CPR meter, Intensive care unit, Randomized clinical trial 4 4 http://jccnc.iums.ac.ir/browse.php?a_code=A-10-988-1&slc_lang=en&sid=1 Alaa Jawad Kadhim alaaj@conursing.uobaghdad.edu.iq 100319475328460014394 100319475328460014394 No University of Baghdad, College of Nursing, Department of Adult Nursing, Baghdad, Iraq.
